RAMMER FOR MOLDING-MACHINES.

Specification of Letters Patent.

Patented May 6,

Application filed July 28, 1917. Serial No. 183,276.

To all whom it may concern:

Be it known that I. GEORGE WVEsLEY WEN- DELL, a citizen of the UnitedStates, residing at J ohnstown, in the county of Oambria, State ofPennsylvania, have invented a new and useful Improvement in Hammers forMolding-Machines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a plan view of amachine embodying my invention;

Fig. 2 is a sectional side elevation of the same on the line 11-11 ofFig. 1;

Fig. 3 is a. view partly in end elevation and partly in verticalsection; and

Fig. 4 is a detail sectional view showing the actuating connections forone of the ramming tools.

My invention has relation to rammers for molding machines, and isdesigned to provide a power-operated rammer of simple and efficientcharacter.

The nature of myinvention will be best understood by reference to theaccompany ing drawings, in which I have shown the preferred embodimentof my invention and which will now be described, it being me mised,however, that various changes can be made in the details ofconstruction, arrangement and combination of the several parts, withoutdeparting from the spirit and scope of my invention as defined in theappended claims.

In these drawings, the numeral 2 designates metal ramming tools, such asare used ordinary hand ramming, but the particular design of which willdepend upon the particular kind of work it is intended to perform. Theserammers are driven by a plurality of eccentrics 3, which are mounted onparallel shafts 4, journaled in suitable bearings on the frame 5. Theeccentrics on each of the shafts are set at an angle to each other aswell as to the eccentrics on the other shafts, so that the ramming toolswill be successively operated. The intermediate shaft 4: is shown asbeing driven by a pulley 6, and is connected by gears 7 with the othereccentric shafts. The several eccentrics are set at difl'erent angles,as shown.

Each of the ramming tools 2 is attached to a helve 8, mounted in a metalsocket 9. In the operation of the machine, it is necessary to providefor adjustments in effective length of the rammers and also to regulatethe weight of the blows. For this purpose, I provide each r'ammer with asleeve 10,

having means at its upper end for connec- 9. 17 is a jam nut threaded onthe rod 16,

and is for the purpose of locking the nut 13 after the proper adjustmenthas been made. 18 is a guide sleeve which screws into the lower endportion of the sleeve 10. 19 designates a bearing block or plug for theupper end of the spring 11. These blocks can be made of differentvertical heights so as to increase or decrease the tension of thespring, and thereby regulate the blow of the rammer.

The machine when in operation is mounted above the mold to be rammed onsuitable supports, the mold passing underneath the machine while beingrammed.

The number, arrangement and character of the rammers can be changed tosuit the particular work being done in any case. The entire machine issimple in its construction and operation, and by adjusting means such asdescribed, the length of stroke of the rammers can be individuallyvaried and the effective action of their blows changed as may bedesired.

I claim:

1. A mold-ramming machine comprising a plurality of reciprocatingramming tools, power means for reciprocating said tools, and springmeans for varying the individual action of each of the tools,substantially as described.

2. A mold-ramming machine, comprising a plurality of removablevertically reciprocating ramming tools, poweractuating means for saidtools, and adjustable spring means for separately adjusting the blow andlength of each tool, substantially as described.

3. A mold-ramming machine comprising a plurality of verticallyreciprocating ramming tools, power-actuating means for successivelyactuating said tools, and adjustable spring means for separatelyadjusting the length and ramming blow of each tool, substantially asdescribed.

a. A mold-rannning machine comprising a plurality of verticallyreciprocating ramming tools, an actuating shaft, eccentrics on saidshaft, actuating connections between the respective eccentrics and therespective ramming tools, and means for separately varying the length ofsaid connections, substantially as described.

5. A mold-ramming machine comprising a plurality of verticallyreciprocating ramming tools, an actuating shaft, eccentrics on saidshaft, actuating connections between the respective eccentrics and therespecti e ramming tools, and means in said connections for separatelyvarying the blow of each tool, substantially as described.

6. A. mold-ramming machine comprising a plurality of intergeared shafts,a plurality of eccentrics on each of said shafts, a plurality ofvertically reciprocable ramming tools, and yieldable actuatingconnections between said tools and the straps of said eccentrics,substantially as described.

7. A mold-ramming machine comprising a plurality of intergeared shafts,a plurality of eccentrics on each of said shafts, a plurality ofvertically reciprocable ramming 30 also the effective blow of the tool,substani tially as described.

In testimony whereof, I-have hereunto set my hand.

GEO. WVESLEY l/VENDELL.
